Test Set-up and Operation Modes
3.1 Principle of Configuration Selection: For emission testing, the EUT was configured to measure its highest possible emission level, with test conditions adapted per the instructions for use. Testing sequence: Radiated emission tests were performed from 2024-10-24 to 2024-10-30. Conducted emission tests were performed on 2024-10-24.
3.2 Equipment and Cable Arrangement:
The test setup involves different configurations for conducted and radiated emissions. For conducted emissions, the EUT is connected via a Line Impedance Stabilization Network (LISN) to the power supply, with an EMI receiver and computer monitoring. For radiated emissions, the EUT is placed on a table (0.8m high) at a distance of 3m from the measurement antenna, connected to an EMI receiver and computer.
3.3 Test Software: No special test software was used.
3.4 Special Accessories and Auxiliary Equipment: A Huawei STF-AL10 cell phone was used during the tests.
3.5 Countermeasures to achieve EMC Compliance: No special measures were employed beyond standard setup.
Conformity Decision Rule
For all EMI tests, compliance is determined by comparing measurement results directly with limits, without considering measurement uncertainties, as the uncertainties are less than the values specified in CISPR 16-4-2.
